With the method GetRoot you can obtain access to the application component. Later at the end of the animation when you stop the timer, you also invoke the method EndAnimation, which on its part re-enables the event handling again. From now, the application will ignore user inputs. In practice, you invoke the method BeginAnimation just in moment your implementation starts the Timer to drive a critical animation. Invoking EndAnimation restores this ability again. Invoking the method BeginAnimation suppresses temporarily the entire application from being able to handle user inputs. In order to protect your application from such critical situations, the application component provides two methods BeginAnimation and EndAnimation. In worst case, the entire application can enter in an incoherent state preventing the user from being able to continue working with the application. Touching the screen or pressing a key on a real keyboard while such transition is in progress may cause the involved GUI components to unexpectedly start operations, which then can interfere with the just active transition. In the short time while the transition is active the both components are (partially) visible and their functionality is eventually accessible for the user. to fade-in a new screen while the old screen is faded-out). You can imagine the situation of a Timer object used to drive a transition between two GUI components (e.g. This, however, is not always the desired behaviour. an indicator GUI component is blinking or a list scrolls its contents. This means in particular, that the user can unhamperedly interact with the application while e.g. Per default, while a Timer is running, the application will continue processing all user inputs. In other words, a Timer object will fire for the first time after the interval Period is elapsed. As you probably know to set a keyframe all you have to do is hit the stopwatch icon next to the property you are trying to keyframe. If the property Begin is set to a value <= 0 (zero), the initial delay is assumed to be the same as the value of the property Period. Accordingly, the timer can be considered as being periodical or one-shot timer. If tListenTimeout() is called while the timer is currently in progress, the.
Afterwards the Timer object disables itself. After the timer expires, listening mode will be exited automatically. In turn, if Period is configured with a value <= 0 (zero), the timer will expire only once after the interval specified in the property Begin. If this property is initialized with a value > 0 (zero), the timer expires periodically as long as it is enabled. The following figure demonstrates the timing behavior of the timer:ĭepending on the initialization of the property Period the Timer object reveals two different behavior modes. For example, when you initialize Begin with the value 500 and later you start the timer, the timer will expire for the first time after 500 milliseconds are elapsed, even if the property Period has been configured with a less value. This property expects again a value expressed in milliseconds. With the second property Begin you can determine an initial delay between the start of a timer and its first expiration. Accordingly, initializing Period with the value 100 causes the timer to expire every 100 milliseconds (means ten times per second). This property expects a value expressed in milliseconds. With the first property Period you determine the interval between two consecutive timer expirations. The Timer object provides two properties permitting you to configure when the timer should expire.
Jet lag can also sometimes cause dizziness, indigestion, nausea, constipation, changes in appetite and mild anxiety.Specify the timer interval and the initial delay

Melatonin tablets are not recommended for jet lag because there's not enough evidence to show they work. The keyboard shortcut to move your layer to the top of the layer panel is CMD + shift + left bracket. Melatonin is a natural hormone released by the body in the evening to let your brain know it's time to sleep. But they can be addictive so should only be used for a short time and if symptoms are severe. Sleeping tablets may be helpful if you're having problems sleeping (insomnia). Jet lag often improves after a few days as your body clock adjusts to the new time zone. Medicines are not usually needed for jet lag. If your trip is short (2 to 3 days), try to eat and sleep at the times you would at home.
